In a bold move that underscores its commitment to innovation and client safety, Harper UK has announced an £800,000 investment to expand and upgrade its fleet of Portable Power Units (PPUs).
These purpose-built systems - long trusted across the marine and offshore sectors - are now being reintroduced with an enhanced specification that sets a new benchmark for operational performance.
Power and performance at the push of a button
Harper UK’s latest generation of PPUs are designed with one clear goal: to make power deployment faster, safer, and more efficient. Engineered as a single-lift, plug-and-play solution, each unit can be fully operational on a vessel’s back deck in as little as 15 minutes, dramatically reducing both downtime and lift operations.
“Our clients want two things: savings and safety,” explains David Duncan, managing director at Harper UK. “This investment delivers both. It’s about getting operations running faster, keeping costs under control, and giving everyone the confidence that safety comes first.”
Engineered for speed, built for safety
Every PPU in the new fleet is a self-contained powerhouse, combining critical systems and storage into a single, compact structure. Each unit includes:
- 240 CFM Compressor
- 400 kVA Tier 5 Generator
- 12 x Welding Plants
- Dedicated storage for cabling, tooling, and consumables — everything needed, securely housed and ready for use
- Integrated Fire Alarm System, installed and tested for rapid response
- Emergency Stop System, offering instant full-system shutdown and seamless vessel integration
- Comprehensive Surround Lighting for improved safety and visibility in all weather conditions
By consolidating these essential systems into one streamlined lift, Harper UK reduces complexity, operational time, and potential risks — all while improving efficiency for marine and offshore crews working in demanding environments.
A safer, smarter future for offshore operations
The expanded fleet reflects Harper UK’s continued mission: to help clients achieve minimal downtime, lower operational costs, and uncompromising safety standards. With every element engineered to simplify deployment and safeguard personnel, the upgraded PPUs embody the company’s philosophy — elite by performance, elite by design.
